WINDIVIILL.

Specification of Letters Patent.

Patented Nov. 20, 1906.

Application filed November 2, 1905. Renewed September 29,1906. SerialNo. 336,807.

To all whom it may concern;

Be it known that I, DAVID Dory, a citizen of the United States, residingat San Angelo, in the county of Tom Green and State of Texas, haveinvented certain new and useful Improvements in I/Vindmills, of whichthe following is a specification.

My invention relates to improvements in windmills, and has for itsobject the provision of anovel mechanism for communicating andconverting the rotary motion of the drivingwheel shaft or spindle of awindmill into a reciprocating motion of the power-transmitting-rod orpump-rod operated by the windmill.

A further object is to construct means for this purpose which willcombine a high degree of efliciency with simplicity and durability andwhich will be comparatively cheap in first cost.

By my construction I am enabled to secure a direct and clear lift of thepump-rod and obviate any frictional contact or rubbing of parts in theoperation of the rod itself.

The invention consists in certain novel features of construction andcombinations and arrangements of elements of the mechanism for utilizingand converting the power of the wind-wheel, as will be described, andmore fully pointed out in the claims.

In the accompanying drawings I have illustrated one eXample'of thephysical em bodiment of my invention constructed according to the bestmode I have so far devised for the practical application of theprinciples thereof.

In the drawings I have disclosed a sufficiency of the mechanism of awindmill to illustrate the application of my invention, it beingunderstood that other appliances of suitable construction may beembodied as necessary or required.

Referring to the figures of the drawings, Figure 1 is a view inelevation of a portion of a supportin tower for a windmill, showing thewindmill and connections in side elevation; and Fig. 2 is a view, partlyin section, paken at right angles to the position shown in The numeral 1designates a supportingtower of ordinary or suitable constructionsurmounted by a cap-piece or turn-table 2, which is secured thereto incustomary manner. The wheel-frame or carriage 3, which supports thewind-wheel and connections, is rotatable on this cap-piece, and at itslower 1 portion said frame is provided with a hollow l circular base 4,between which base and the turn-table or cap-piece 2 a series ofantifriction-balls 5 are interposed, traveling in a groove or ball-racebetween the members, as usual.

The wind-wheel 6 is supported on its shaft or spindle 7, which shaft isjournaled in a boX in the frame or carriage 3. The shaft 7 is projectedthrough the frame on its side opposite the wheel 6, and on its end agear-wheel 8 is secured, which meshes with or engages the teeth of asimilar wheel 9, journaled on a stud or short shaft 10 on the frame 3.These two gear-wheels 8 and 9 are connected by a pitman composed of arod 11 and a sleeve 11, in which said rod is slidably disposed. Thepower-transmitting or pump rod 14 is connected to sleeve 11 by a link15, said link being pivoted at 16 to said sleeve.

The directing-vane 17 is supported from the frame by the vertical arm 18and the horizontal arm 19, the parts being secured by bolts or rivets,and this vane serves as a counterbalancing-weight for the wheel and itssupporting-frame, as usual.

In operation as the wind-wheel revolves by the action of the wind itsrotary motion is communicated through its shaft to the gearwheel 8,which in turn communicates its motion to the wheel 9. The rotary motionof the two wheels is converted into a reciprocating movement by thevertical rising and falling of the pitman caused by the action of thewheels to which the pitman is connected. Thus the link and powertransmitting or are made to partake of a reciprocatory verticalmovement, which may be utilized as power in usual manner.

The upper end. of the pitman is slotted at its pivoted point 12, as isillustrated in Fig. 2, to permit of a limited adjustment of the parts.

From the above description, taken in connection with the drawings, it isevident that I have produced a mechanism which fulfils all theconditions set forth as the purpose or object of my invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, 1s-

1. In a windmill, the combination with a supporting-tower having aturn-table thereon, a wheel-frame having a base and antifriction-bearingbetween said base and turnpump rods which are attached to the pitman.

table, a wind-wheel with its shaft ournaled in the frame, a gear-Wheeljourna-led in the frame, and a similar wheel meshing there with locatedon the wheel-shaft, a pitman connected to said gear-wheels, and a transmitting-rod connected to said pitman.

2. In a device as described, the combination with a supporting-tower andframe, of a wind-wheel having its shaft journaled in the frame and agear-wheel on said shaft, a gearwheel journaled in the frame engagingthe first gear-wheel, a pitman connecting the gear-wheels, and apower-transmitting rod connected to said pitman.

3. The combination with a supportingframe of a drive-wheel having itsshaft journaled therein, a gear-wheel on the shaft and a similar wheelmeshing therewith journaled in the frame, a pitman connecting saidgearwheels, and connections to the pitman whereby the rotary motion ofthe drive-wheel is converted into reciprocatory movement of theconnections.

4. In a windmill, the combination with a supporting-tower and rotatablewheel-frame, of a wind-wheel with its shaft journaled in said frame anda gear-wheel on said shaft, a similar gear-wheel ournaled in the frameand meshing with the first gear-wheel, a pitman pivotally connected atits ends with the gear-wheels, a powertransmitting rod, and a linkconnecting said rod and the pitman, substantially as described.

In testimony whereof I afIiX my signature in presence of two witnesses.
